Instrument having a blood pressure measuring function

Abstract

The instrument according to the present invention includes a band-like belt worn around a wrist, and a main body disposed at a portion of the belt corresponding to the volar surface or the dorsal surface of the wrist. An element for executing a blood pressure measuring function is mounted in the main body. A battery for supplying electric power to the element mounted in the main body is disposed at a portion of the belt located away from the main body in the circumferential direction around the wrist. A wire is provided in the belt, extends in the circumferential direction along the fluid bag, and electrically connects the element mounted in the main body and the battery. In the belt, the wire is disposed away from the fluid bag in the width direction perpendicular to the circumferential direction and extends along an edge section of the belt.

The invention claimed is: 
     
       1. An instrument having a blood pressure measuring function and configured to be worn around a wrist, the instrument comprising:
 a band-like belt configured to be worn around the wrist in a circumferential direction, the band-like belt including an edge extending in the circumferential direction and a fluid bag that extends in the circumferential direction to compress an artery of the wrist; and 
 a main body which is disposed at a first portion of the band-like belt corresponding to at least one of a volar surface and/or a dorsal surface of the wrist, in which a pressure control unit that supplies air to the fluid bag and controls pressure is mounted as an element for executing the blood pressure measuring function, wherein: 
 a battery which supplies electric power to the element mounted in the main body is disposed at a second portion of the band-like belt away from the main body in the circumferential direction, 
 a wire which enters the band-like belt directly from the main body and extends in the circumferential direction along the fluid bag is provided in the band-like belt, the wire electrically connecting the battery and the element mounted in the main body, and 
 in a planar view viewed from a thickness direction perpendicular to an outer circumferential surface of the band-like belt, the wire is spaced apart from the fluid bag, and the wire is disposed between the fluid bag and the edge of the band-like belt. 
 
     
     
       2. The instrument according to  claim 1 , wherein
 one end section and an other end section of the band-like belt overlap in the circumferential direction such that the one end section is located on an inner side and the other end section is located on an outer side in a state where the band-like belt is worn around the wrist, and 
 the battery is disposed on the other end section of the belt located on the outer side at a portion that overlaps the one end section located on the inner side. 
 
     
     
       3. The instrument according to  claim 1 , wherein an entirety of the battery is only disposed at the second portion of the band-like belt. 
     
     
       4. The instrument according to  claim 1 , wherein the wire does not overlap the fluid bag in the planar view. 
     
     
       5. The instrument according to  claim 1 , wherein the wire extends from the main body to the battery without overlapping with the fluid bag in the planar view. 
     
     
       6. The instrument according to  claim 1 , wherein the wire does not extend outside the main body and the band-like belt.
